Variables

  Type Name Description
Public variable TArray< TObjectPtr< UDeviceProfile > > Profiles Holds the collection of managed profiles.

Functions

  Type Name Description
Public function void

ChangeTaggedFragmentState ( FName FragmentTag,
bool bNewState
)

 Enable/Disable a tagged fragment of the active device profile.
Public function UDeviceProfile *

CreateProfile ( const FString& ProfileName,
const FString& ProfileType,
const FString& ParentName,
const TCHAR* ConfigPlatform
)

 Create a copy of a device profile from a copy.
Public function void Delete a profile.
Public function bool

DoActiveProfilesReference ( const TSet< FString >& DeviceProfilesToQuery
)

 Examine the currently active or overridden profile for references to entries in DeviceProfilesToQuery
Public function UDeviceProfile *

FindProfile ( const FString& ProfileName,
bool bCreateProfileOnFail
)

 Find a profile based on the name.
Public function Static TMap< FName, FString >

GatherDeviceProfileCVars ( const FString& DeviceProfileName,
EDeviceProfileMode GatherMode
)

 Walk the device profile/fragment chain to get the final set ot CVars in a unified way
Public function Static UDeviceProfileManager &

Get ( bool bFromPostCDOContruct
)

  
Public function Const const FSelectedFragmentProperties * Return the selected fragment property from the currently active device profile.
Public function const FString

GetActiveDeviceProfileMatchedFragmentsString ( bool bEnabledOnly,
bool bIncludeTags,
bool bAlphaSort
)

 Get a string containing the current matched fragment list.
Public function const FString Get the current active profile name.
Public function Const UDeviceProfile * Get the selected device profile
Public function Const void

GetAllPossibleParentProfiles ( const UDeviceProfile* ChildProfile,
TArray< UDeviceProfile* >& PossibleParentProfiles
)

 Get a list of all possible parent profiles for a given device profile
Public function Static TMap< FName, TSet< FString > > Gather all the cvars from the static device profile and then add all of the possible cvars+values from the dynamic/matched rule fragments.
Public function Static const FString Get the selected device profile name, either the platform name, or the name provided by a Device Profile Selector Module.
Public function Const UDeviceProfile * Get the currently previewing device profile. Can be null.
Public function void

GetProfileConfigFiles ( TArray< FString >& OutConfigFiles
)

 Returns the config files for all loaded device profiles, this will include platform-specific ones
Public function Static bool

GetScalabilityCVar ( const FString& CvarName,
int32& OutValue
)

 Retrieves the value of a scalability group cvar if it was set by the active device profile.
Public function Static bool

GetScalabilityCVar ( const FString& CvarName,
float& OutValue
)

 Retrieves the value of a scalability group cvar if it was set by the active device profile.
Public function bool

HasLoadableProfileName ( const FString& ProfileName,
FName OptionalPlatformName
)

 Tests to see if a named device profile is available to call CreateProfile with.
Public function Static void

InitializeCVarsForActiveDeviceProfile ( bool bPushSettings,
bool bIsDeviceProfilePreview,
bool bForceReload
)

 Startup and select the active device profile Then Init the CVars from this profile and it's Device profile parent tree.
Public function void Load the device profiles from the config file.
Public function FOnActiveDeviceProfileChanged & Returns a delegate that is invoked when the active device profile changes
Public function FOnDeviceProfileManagerUpdated & Returns a delegate that is invoked when manager is updated.
Public function void

ReapplyDeviceProfile ( bool bForceReload
)

 Reapplies the device profile.
Public function void Restore the device profile to the default for this device
Public function void

SaveProfiles ( bool bSaveToDefaults
)

 Save the device profiles.
Public function void Overrides the device profile. The original profile can be restored with RestoreDefaultDeviceProfile

Overridden from UObject

  Type Name Description
Public function Virtual void Called after the C++ constructor has run on the Class Default Object (CDO) for a class.

Enums

  Type Name Description
Public enum EDeviceProfileMode    

Constants

Name Description
BackupSuffix Add to profile to get load time backup.
DeviceProfileManagerSingleton  
DeviceProfileScalabilityCVars Stores any scalability group settings set by the active device profile.
PlatformFragmentsSelected The list of fragments that have been selected by the active profile.
PushedSettings Original values of all the CVars modified by the DP. Used to undo the DP before applying new state.

Deprecated Functions

  Type Name Description
Public function Static const FString Use either GetActiveDeviceProfileName to have the current active device profile or GetPlatformDeviceProfileName to have the default one. Note, GetActiveDeviceProfileName will fallback on GetPlatformDeviceProfileName, if there is no active device profile
